The present invention relates to a wiring member fixing structure for fixing a wiring member such as a flat cable at a predetermined position.

  An audiovisual apparatus such as an amplifier that amplifies an audio signal may include a plurality of wiring members that connect between boards and a large-sized component such as a heat sink that increases in temperature inside the casing. While the wiring member such as a flexible cord is connected to the substrate at both ends, the position of the intermediate portion is not fixed, so it is a predetermined position in the housing using a fixing member such as a binder at the manufacturing stage, It is mechanically fixed so as to be separated from high temperature components such as a heat sink. In some cases, the substrate is fixed so as not to be in direct contact with the discarded substrate. However, in these audiovisual equipment, the internal structure including the wiring becomes complicated while downsizing, and there may be a case where a sufficient space is not provided between the wiring member and other parts.

  In the wiring member fixing structure of the electronic device casing, it is desirable that the number of man-hours required for fixing the wiring member and the cost required for manufacturing are smaller by using the wiring member fixing structure that is easy to mount. Therefore, conventionally, in order to reduce the member cost and the manufacturing cost, and to ensure the distance between the wire and the heat generating component, one or a plurality of wire holders are disposed on the discarded substrate cut out from the printed wiring board. There is a wire holder using a printed wiring board characterized by being formed (Patent Document 1).

  Conventionally, a pair of wires extending from both ends of a cold cathode tube disposed behind the liquid crystal cell in the liquid crystal module is connected to a main substrate made of a printed wiring board, and the cold cathode tube is connected via the main substrate. In a thin display device in which the liquid crystal cell is illuminated from behind by causing the liquid crystal cell to emit light, the liquid crystal cell has a lock plate formed at the center of the lower edge with a pair of recesses that can be fitted to the wires, and the lower edge of the lock plate A pair of trapezoidal projections having inclined side surfaces at both ends are integrally projected, and a pair of lock holes facing each of the projections are provided through the main board with both wires interposed therebetween. An inlet portion that is significantly larger than the lower end width of each projecting portion is formed on one end side of each, and a rear end portion that is smaller than the lower end width of each projecting portion is formed on the other end side of each lock hole, Each protrusion of the lock plate is connected to the entrance of each lock hole By inserting, each recess is fitted to each wiring, the lock plate is slid to the back end, and the inclined side surfaces of each projection are engaged with the lower edge of the back end, and the lock plate and the main board And a thin display device characterized in that each wiring is sandwiched (Patent Document 2). The lock plate may be a discarded substrate formed on the main substrate.

  However, in order to fix the intermediate portion of the wiring member such as a flexible cord by the structure of diverting the conventional discarded substrate as in Patent Document 1 or 2, the position of the wiring member at the front and rear portions of the fixed position is not determined. Therefore, there is a problem that the wiring member and these components may come into contact with each other when a sufficient separation space from other components is not provided. If the number of points for fixing the wiring member is increased to a plurality, the work required for attachment becomes difficult, and there is a problem that the number of work steps increases. In addition, in the case of preparing another dedicated member for fixing the wiring member, there is a problem that it becomes a cost increasing factor.

Are opposed to each other by a connecting member passing through the cutout so as to be constituted by one plane of the single substrate, and the wiring member is sandwiched between the respective planes of the first substrate and the second substrate, and the housing Fixed to.

  Preferably, in the wiring member fixing structure of the electronic device casing according to the present invention, the connecting member is fixed at both ends across the slit formed in the single substrate, and the single substrate is divided into two along the slit. In some cases, the first substrate and the second substrate of the wiring fixing member are formed, and the connecting member is deformed to hold the wiring member between the planes of the first substrate and the second substrate.

  The wiring member fixing structure for an electronic device casing according to the present invention includes an insertion hole in which at least one of the first substrate and the second substrate of the wiring fixing member is inserted and positioned through the wiring member. Passes through the insertion hole.

  In the wiring member fixing structure of the electronic device casing of the present invention, the wiring fixing member further includes a screw for fixing the two substrates to the casing, and the substrate is formed with a through-hole through which the screw passes. The through holes are arranged to communicate with each other when they are opposed to each other by the connecting member.

  Moreover, the electronic device or audiovisual device of the present invention includes the wiring member fixing structure of the electronic device casing.

Also, the wiring member fixing method for an electronic device casing of the present invention is a wiring fixing method for fixing a wiring member at a predetermined position of the casing of the electronic device casing, and the step of providing a slit on a single substrate of a predetermined shape A step of fixing both ends of the connecting member constituted by one or a plurality of tin-plated wires across the slit of the single substrate, and the single substrate is divided into two along the slit and is larger than the width dimension of the wiring member Forming a wiring fixing member including a first substrate and a second substrate connected by a connecting member including a plane having a width dimension, and wiring between the planes of the first substrate and the second substrate by deforming the connecting member; a step of holding the member, seen at least containing a step of fixing the wiring fixing member that sandwich the wire member at a predetermined position of the housing, the first and second substrates were allowed to face the coupling member If arranged to communicate It has a notch and the respective planes of the first substrate and the second substrate is brought to face the connecting member passing through the notch to be formed by one flat surface of one substrate.

  The operation of the present invention will be described below.

  The wiring member fixing structure for an electronic device casing of the present invention includes a wiring member such as a flat cable and a wiring fixing member for fixing the wiring member to a predetermined position of the casing. The wiring fixing member includes a first substrate and a second substrate which are discarded substrates at the stage of manufacturing an electronic device. The first substrate and the second substrate include a plane having a width dimension larger than the width dimension of the wiring member, and are connected by the connecting member. That is, since the wiring fixing member includes the first substrate and the second substrate, and the connecting member that connects the first substrate and the second substrate, the wiring member is the first substrate and the second substrate that are opposed to each other by the connecting member. It is sandwiched between the respective planes of the substrate and fixed to the housing.

  The connecting member may be a connecting member having mobility such as a hinge connecting the first substrate and the second substrate. Alternatively, in order to simplify the structure and reduce the increase in cost, the connecting member is composed of one or more bent tin-plated wires (TA wire, tin-plated copper soft wire) that can be inserted in the electronic component mounting process. May be. In this wiring member fixing structure, the first substrate and the second substrate of the wiring fixing member are formed by dividing a single substrate of a predetermined shape into two, and each plane sandwiching the wiring member is formed of a single substrate. It is made to oppose by the connection member so that it may be comprised by one plane. That is, in the wiring fixing method of fixing the wiring member at a predetermined position of the casing of the electronic device casing, a slit is provided on a single substrate of a predetermined shape, and the connecting member as described above straddling the slit of the single substrate. After fixing the wiring board, the one board is divided into two along the slit, and the wiring fixing member including the first board and the second board connected by the connecting member including a plane having a width dimension larger than the width dimension of the wiring member. Form.

  Therefore, when the connecting member is deformed and the wiring member is held between the planes of the first substrate and the second substrate, the connecting member holding the wiring member can be fixed at a predetermined position of the housing. In the wiring member fixing structure, when both ends of the connecting member are fixed across the slit formed in the single substrate and the single substrate is divided into two along the slit, the first and second substrates of the wiring fixing member are arranged. Two substrates are formed, and the connecting member is deformed to sandwich the wiring member between the planes of the first substrate and the second substrate. Since the first substrate and the second substrate include a plane having a width dimension larger than the width dimension of the wiring member, if the wiring board is formed with a predetermined length in the length dimension direction sandwiching the wiring member, the wiring member is predetermined. It can be arranged in a state of being molded in When the connecting member is constituted by one or a plurality of bent tin-plated wires, both ends of the tin-plated wire become the first substrate and the second substrate across the slit of one substrate in the mounting process of the electronic component. Secure to each part. Then, when the single substrate is divided into two along the slit, a wiring fixing member including the first substrate and the second substrate connected by the tin plating wire can be formed.

  As a result, since the flexible intermediate portion of the wiring member such as the cord can be fixed on the plane of the first substrate and the second substrate, the position of the long intermediate portion of the wiring member can be determined. Even when there is not enough space for separation from other parts, the work required for installation is easy with a small number of parts. It is possible to prevent contact with components that are likely to become high temperature.

  In the wiring member fixing structure of the electronic device casing according to the present invention, when the first substrate and the second substrate of the wiring fixing member are formed by dividing a single substrate of a predetermined shape into two parts, the first member and the second substrate are opposed to each other by a connecting member. If the connecting member is formed of a tin-plated wire, it is preferable that the connecting member pass through the notch. In other words, the notches are arranged in the first substrate and the second substrate so as to communicate with each other, and the wiring member is sandwiched between the planes of the first substrate and the second substrate by bending and deforming the tin-plated wire as the connecting member. When the total length of the tin-plated wire is designed so that the tin-plated wire passes through the notch, the direction in which the connecting member is deformed can be defined by the notch. The distance between the first substrate and the second substrate can be adjusted. Therefore, there is an advantage that an operation of fixing a wiring member such as a flat cable in a predetermined position becomes easy.

  In addition, at least one of the first substrate and the second substrate of the wiring fixing member may have an insertion hole through which the wiring member is inserted and positioned. If the wiring member passes through the insertion hole of the first substrate or the second substrate, the wiring member is temporarily fixed by the insertion hole, so that there is an advantage that the operation of fixing the wiring member at a predetermined position becomes easy. is there. When the wiring fixing member further includes a screw for fixing the two substrates to the housing, a through hole through which the screw passes is formed in the plane of the substrate, and the through hole is opposed to the connecting member It is arranged to communicate with. In other words, in the wiring member fixing structure of the electronic device casing, the wiring fixing member can be easily fixed using a screw inside the casing of the electronic device or the audiovisual device, and the wiring is fixed by fixing the screw. Since the wiring member can be fixed at a predetermined position together with the member, there is an advantage that the number of work steps can be reduced.

  The wiring member fixing structure of the electronic device casing of the present invention makes it easy to fix a wiring member such as a flat cable in a predetermined position in the casing of an electronic device or an audiovisual device including a heat generating component, and When the discarded substrate is diverted, it is possible to provide a wiring member fixing structure with a simple structure and a small increase in cost.

(Example 1) It is a figure explaining the wiring fixing member 10a of the electronic device housing | casing by preferable embodiment of this invention. (Example 2)

  Hereinafter, a wiring member fixing structure and a wiring member fixing method of an electronic device casing according to preferred embodiments of the present invention and an electronic device or an audiovisual device using the same will be described, but the present invention is not limited to these embodiments.

  FIG. 1 and FIG. 2 are diagrams for explaining a wiring member fixing structure 1 of an electronic device casing according to a preferred embodiment of the present invention. Specifically, FIG. 1 is a side view for explaining a side view of a part of the front side of the electronic device casing, and FIG. 2 is a plan view of the portion of FIG. 3 and 4 are diagrams for explaining the wiring fixing member 10 of the electronic device casing. Specifically, FIGS. 3A and 4A are front views of the wiring fixing member 10. FIG. FIG. 3B and FIG. 4B are cross-sectional views of the wiring fixing member 10. The electronic device casing including the wiring member fixing structure 1 is specifically an AV receiver including an amplifier that amplifies an audio signal. In order to make the figure easy to understand, the entire configuration and the wiring member fixing structure 1 The illustration of a part of the configuration unnecessary for the description is omitted.

  The wiring member fixing structure 1 of this embodiment fixes a flat cable 8 as a wiring member at a predetermined position in a housing of an AV receiver including a heat sink 5 that generates heat. The wiring member fixing structure 1 shown in FIGS. 1 and 2 includes a metal chassis 2, a front panel 3, a bottom foot 4, and a heat sink 5 attached to the chassis 2, and a substrate 6 ( 6a, 6b, 6c), a heat generating semiconductor element 7 fixed to the heat sink 5 and the substrate 6c, a flat cable 8 connecting and connecting the substrates 6a and 6b, a wiring fixing member 10 for fixing the flat cable 8, and And a screw 9. The flat cable 8 includes a connector portion 8a corresponding to the terminal of the substrate 6a and a connector portion 8b corresponding to the terminal of the substrate 6b at both ends.

  That is, in the wiring member fixing structure 1, the flat cable 8 that connects the substrate 6 a fixed to the front panel 3 and the substrate 6 b disposed on the rear side across the heat sink 5 is illustrated in the plan view of FIG. 2. Such a structure is arranged through a slight gap between the heat sink 5 and the chassis 2. Since the laminated member of the flat cable 8 contains a component that is weak against high heat, it is preferable not to directly touch the heat sink 5 that dissipates the heat of the semiconductor element 7 that generates heat. Further, it is preferable not to touch the chassis 2 directly in terms of preventing abnormal noise from coming into contact with the chassis 2 due to vibration and avoiding the influence of unnecessary radiation. Therefore, in this wiring member fixing structure 1, the intermediate portion of the flat cable 8 is fixed at a predetermined position by the wiring fixing member 10 using a discarded substrate.

  As shown in FIGS. 3 and 4, the wiring fixing member 10 includes a first substrate 11 and a second substrate 12 formed by dividing a single substrate having a predetermined shape into two parts. The intermediate portion of the flat cable 8 is held by the two substrates 12. The first substrate 11 and the second substrate 12 are formed using a portion corresponding to a discarded substrate at the stage of manufacturing the substrate 6 of the AV receiver. The first substrate 11 and the second substrate 12 are formed so as to respectively include a plane 17 having a width dimension larger than the width dimension of the flat cable 8 so that the flat cable 8 can be sandwiched entirely. In the wiring fixing member 10, the first substrate 11 and the second substrate 12 are opposed to each other by a connecting member 20 described later so that the flat cable 8 is held by one plane 17 at the stage of a single substrate.

  The first substrate 11 and the second substrate 12 of the wiring fixing member 10 are formed by dividing a single substrate having a predetermined shape into which these are connected. That is, a slit 13 is formed between the first substrate 11 and the second substrate 12 so as to divide into two parts, leaving a small connecting portion 14, so that one sheet is formed along the slit 13 in the manufacturing stage. When the substrate is divided into two, the first substrate 11 and the second substrate 12 of the wiring fixing member 10 are formed. The first substrate 11 and the second substrate 12 are each formed with a plurality of cutouts 15 and through-holes 16 arranged to communicate with each other when facing each other by a connecting member 20 described later.

  The connecting member 20 of the present embodiment is composed of six tin-plated wires formed to a predetermined length. The connecting member 20 is a member called a TA wire or a jumper wire, and is inserted into a predetermined position of the first substrate 11 and the second substrate 12 and fixed by soldering both ends in the component mounting stage on the substrate 6. Is done. As shown in FIG. 3, the connecting member 20 straddles the slit 13 at the stage of a single substrate, and both ends thereof are fixed to the first substrate 11 and the second substrate 12. When the substrate is divided into two, the first substrate 11 and the second substrate 12 can be formed, and the first substrate 11 and the second substrate 12 can be connected so as not to be separated.

  Further, since the connecting member 20 composed of six tin-plated wires can be easily deformed by a predetermined manufacturing process at the manufacturing stage, the planes 17 of the first substrate 11 and the second substrate 12 are opposed to each other. Thus, the flat cable 8 can be pinched. When a single substrate in a state as shown in FIG. 3 is divided into two along the slit 13 to form the first substrate 11 and the second substrate 12, the operation of a hinge including a joint portion that rotates the connecting member 20 is performed. If it deform | transforms into, the wiring fixing member 10 which clamps the flat cable 8 like FIG. 4 with two thrown-out boards can be comprised by a series of work. Therefore, there is an advantage that an operation of fixing a wiring member such as a flat cable in a predetermined position becomes easy.

  Since the first substrate 11 and the second substrate 12 of the wiring fixing member 10 are formed by dividing the single substrate into two along the slit 13, the slit 13 is composed of six tin-plated wires. A notch 15 corresponding to the connecting member 20 is defined. That is, the notch 15 corresponding to the connecting member 20 is disposed so as to communicate with each other when the first substrate 11 and the second substrate 12 are opposed to each other by the connecting member 20, as shown in FIG. Thus, a part of the connecting member 20 passes therethrough. When the flat cable 8 is sandwiched between the flat surfaces 17 of the first substrate 11 and the second substrate 12 by bending and deforming the tin-plated wire as the connecting member 20, the tin-plated wire passes through these notches 15. By designing the overall length of the tin-plated wire, the direction in which the connecting member 20 is deformed can be defined by the notch 15, and further, the distance between the first substrate 11 and the second substrate 12 holding the flat cable 8 can be determined. There is an advantage that can be adjusted.

  Moreover, in this wiring member fixing structure 1, the wiring fixing member 10 using a discarded substrate is connected to the heat sink 5 using screws 9, and the intermediate portion of the flat cable 8 is fixed to a predetermined position in the housing. The first substrate 11 and the second substrate 12 of the wiring fixing member 10 are formed with two sets of through holes 16 through which the screws 9 pass. The through holes 16 communicate with each other when they are opposed to each other by the connecting member 20. Are arranged as follows. Therefore, in the step of forming the wiring fixing member 10 using the discarded substrate, when the first substrate 11 and the second substrate 12 are formed by dividing the single substrate into two along the slits 13, the flat cable 8 is turned into 2 pieces. Since the connecting member 20 connects them so that the through holes through which screws for fixing to the housing pass are held between the two discarded substrates, work for fixing the wiring member such as a flat cable in a predetermined position There is an advantage that becomes easier. That is, in this wiring member fixing structure 1, the wiring fixing member 10 can be easily fixed using the screws 9 inside the housing.

  Therefore, the wiring member fixing method using the above-described wiring member fixing structure 1 includes a step of providing the slit 13 on a single substrate of a predetermined shape, a step of fixing the connecting member 20 across the slit 13 of the single substrate, and a slit The wiring fixing member 10 including the first substrate 11 and the second substrate 12 connected by a connecting member including a plane 17 having a width dimension larger than the width dimension of the flat cable 8 by dividing the single substrate into two along 13. At least the step of forming. Further, in this wiring member fixing method, the connecting member 20 is deformed to sandwich the flat cable 8 between the flat surfaces 17 of the first substrate 11 and the second substrate 12, and the wiring fixing is performed by sandwiching the flat cable 8. Fixing the member 10 to a predetermined position of the housing with the screw 9. When the connecting member 20 is constituted by one or more bent tin-plated wires, a step of fixing both ends of the tin-plated wire across the slit 13 of the single substrate, and a single substrate along the slit 13 Forming the wiring fixing member 10 including the first substrate 11 and the second substrate 12 connected to each other by a tin-plated wire.

  Therefore, this wiring member fixing method can fix the flat cable 8 together with the wiring fixing member 10 at a predetermined position by fixing the screw 9 in the casing of the electronic device or the audiovisual device including the component that generates heat. The work of fixing at a predetermined position becomes easy, and when the discarded substrate is diverted, there is an advantage that the number of work steps can be reduced because the structure is simple and the cost is not increased.

  The connecting member 20 is not limited to the case of the six tin-plated wires of the present embodiment, but may be another easily deformable wire or member such as a metal plate. May be. The number of tin-plated wires may be one or plural as in the above embodiment. Further, the connecting member 20 may be a hinge-like member including a rotating joint portion.

  FIG. 5 is a diagram for explaining a wiring fixing member 10a used in the wiring member fixing structure 1 according to another embodiment of the present invention. Specifically, the wiring fixing member 10a is different in that the first substrate 11 has an insertion hole 18 through which the flat cable 8 is inserted and positioned, and the others have almost the same configuration and size. . Therefore, the same parts as those in the previous embodiment are denoted by the same reference numerals, and the description and illustration are omitted.

  Specifically, the insertion hole 18 of the first substrate 11 of the wiring fixing member 10a has a part that is wider than the width of the flat cable 8 so that the operation of inserting the flat cable 8 is easy. The hole is formed in a substantially T-shape that is partly cut out to communicate with the peripheral portion, and the flat cable 8 is allowed to pass therethrough for relative positioning of the flat cable 8 and the wiring fixing member 10a. It is an insertion hole for performing. Therefore, if the flat cable 8 passes through the insertion hole 18 of the first substrate 11 or the second substrate 12, the flat cable 8 is temporarily fixed by the insertion hole 18, so that the flat cable is used by using the wiring fixing member 10a. The operation of fixing 8 at a predetermined position becomes easy. The insertion hole 18 may be provided in at least one of the first substrate 11 and the second substrate 12, and may define another shape corresponding to the dimensional shape of the flat cable 8.

  In addition, this invention is not limited to the said Example. The wiring member fixed by the wiring fixing member 10 or 10a is not limited to the flat cable 8 as described above, but may be other covered electric wires, and of course, it can be used for a structure for fixing a plurality of wiring members. . Further, the screw 9 for fixing the wiring fixing member 10 or 10a and the heat sink 5 may be substituted by a binder, another engaging means, or an adhesive using an adhesive.

  The wiring member fixing structure and method of the present invention can be applied not only to audiovisual equipment such as an amplifier that amplifies an audio signal, but also to wiring member fixing structures of other audiovisual equipment or equipment such as an electronic computer.
